The iPhone 4 was revealed by Apple CEO Steve Jobs in his WWDC keynote presentation in early June of 2010. During this keynote presentation, the public was given a look at the massive addition of new features (when compared to the prior model, the 3GS). The initial response has been overwhelming, as these features will make this phone perhaps the most powerful on the market. Below are the features the consumer will experience with the iPhone 4.

The Features:

Higher Resolutions

The iPhone 4 boasts resolutions well surpassing its predecessor. The new "retina display" can be found on the 3.5-inch, 960x640 pixels screen. The new display also features 326 pixels per inch (which is four times as many as the iPhone 3GS) as well as an 800:1 contrast ratio.

5-Megapixel Camera

Once again, this is a vast improvement over the iPhone 3GS's 3-megapixel camera. Not only will pictures taken on this phone appear more crisp and clear, but the camera also features 5x digital zoom, tap to focus, and LED flash.

HD Video Recording And Editing

Although the iPhone 3GS has video recording, it left much to be desired. The iPhone 4 will allow for high definition video recording as well as an editing function. The HD quality will be at 720p and the recording will feature "tap to focus." Early criticsm of the video feature suggests that the video recording will draw a substantial amount of battery power, and the ability to share video via the internet (from the iPhone) will put a significant strain on one's data usage plan with AT&T.


Video Calling

The iPhone 4 will allow the user to make video phone calls through an application known as "FaceTime." As of the time this article was written, FaceTime only allows video phone call via WiFi connection (and not 3G or other cellular connection). Furthermore, the user will only be able to connect with other iPhone 4 users who have the FaceTime application installed.

Longer Battery Life

As anyone with a cell phone is aware, battery life is perhaps one of the most important features of any device. Apple estimates the phone will allow for 7 hours of 3G talk time, 6 hours of browsing on 3G (or 10 hours of browsing on WiFi), 10 hours of video, 40 hours of music, and 300 hours of standby. This is a fairly significant improvement over the iPhone 3GS and compares favorably with other smart phones on the market.


One of the primary criticsms of the iPhone since its creation was that it does not have the ability to multitask. The iPhone 4 puts these criticsms to rest as its users will now be able to multitask (i.e. run multiple applications simultaneously). When the user switches between applications and revisits previous applications, the application remembers where the user left off. The best part is, Apple claims this multitasking feature will not interfere with the speed and performance of the device.


It's clear that with these additional features, Apple has created a smart phone device that will once again revolutionize the way the average consumer interacts and communicates on a daily basis. Consumers talked and Apple listened.
